When BBC London uploaded a video of the Carnaby Street Christmas lights being switched on last week, the comments section filled with thousands of people reacting to what they saw.
But, it wasn't the bright lights or the pretty fireworks that they were reacting to, it was the sea of spectators filming on their phones.
"Remember when we used to look at stuff directly with our eyes? Those were the good old days," said one comment. Another simply said: "It's such a sad sad sight."
